It seems like you have solve the smell problem with the oil separator.
Other smell are The fuel filter connections tend to leak. I used a larger o-ring to stop the leak from the sensor. Hose was also leaking, replaced.
If oily smell, the oil drops on the dfp or exhaust that is right under HVAC air filter in the right side/firewall engine compartment.
A terrible design.
IND Mechanic said lower oil pan $400. replaced but that was not source of the leak.
Then said upper oil pan. $1000 job.
Another IND said upper oil pan was definitely not the source, but could not locate the source.
Oil in the bell housing, so rear main seal or draining from the oil cooler.
2009 bluetec with 110,000 miles. Had turbo, flapper motor, front wheel bearings and glow plug relay replaced. Seems to need alot of repairs.
The oil leak is splashing even to the alternator and could short out some computer and sensor. Half to 1 liter oil loss per 6,000 mile. AT-200 leak stop didn't work or made it worse.
Pull the engine and fix both of them at same time ($2500?) or just use until it dies?
